OIL AND FUEL INFORMATION

10

WARNING: Gasoline is extremely flammable.

Ignited Vapors may explode. Always stop the

engine and allow it to cool before filling the fuel

tank. Do not smoke while filling the tank. Keep

sparks and open flames at a distance from the

area.

WARNING: Remove fuel cap slowly to avoid

injury from fuel spray. Never operate the unit

without the fuel cap securely in place.

WARNING: Add fuel in a clean, well

ventilated area outdoors. Wipe up any spilled

fuel immediately. Avoid creating a source of

ignition for spilt fuel. Do not start the engine

until fuel vapors dissipate.

NOTE: Dispose of the old fuel/oil mix in accordance to

Federal, State, and Local regulations.

OIL AND FUEL MIXING INSTRUCTIONS

Old and/or improperly mixed fuel are the main reasons

for the unit not running properly. Be sure to use fresh,

clean unleaded fuel. Follow the instructions carefully for

the proper fuel/oil mixture.

Definition of Blended Fuels

Today's fuels are often a blend of gasoline and

oxygenates such as ethanol, methanol or MTBE (ether).

Alcohol-blended fuel absorbs water. As little as 1%

water in the fuel can make fuel and oil separate. It forms

acids when stored. When using alcohol-blended fuel,

use fresh fuel (less than 60 days old).

Using Blended Fuels

If you choose to use a blended fuel, or its use is

unavoidable, follow recommended precautions.

• Always use fresh fuel mix per your operator's manual.

• Use the fuel additive STA-BIL® or an equivalent.

• Always agitate the fuel mix before fueling the unit.

• Drain the tank and run the engine dry before storing

the unit.

Using Fuel Additives

The use of fuel additive, such as STA-BIL® Gas Stabilizer

or an equivalent, will inhibit corrosion and minimize the

formation of gum deposits. Using a fuel additive can keep

fuel from forming harmful deposits in the carburetor for up

to six (6) months. Add 0.8 oz. (23 ml.) of fuel additive per

gallon of fuel according to the instructions on the container.

NEVER add fuel additives directly to the unit's fuel tank.

CAUTION: For proper engine operation and

maximum reliability, pay strict attention to the

oil and fuel mixing instructions on the 2-cycle

oil container. Using improperly mixed fuel can

severely damage the engine.

Thoroughly mix the proper ratio of 2-cycle engine oil

with unleaded gasoline in a separate fuel can. Use a 32:1

fuel/oil ratio. Do not mix them directly in the engine fuel

tank. See the table below for specific gas and oil mixing

ratios.

NOTE: One gallon (3.8 liters) of unleaded gasoline mixed

with one 4 oz. (120 ml.) bottle of 2 CYCLE OIL

makes a 32:1 fuel/oil ratio.

MAINTENANCE AND REPAIR INSTRUCTIONS

18

Checking the fuel mixture, cleaning the air filter, and

adjusting the idle speed screw should solve most engine

problems.

If not and:

• The engine will not idle,

• The engine hesitates or stalls on acceleration,

• There is a loss of engine power,

have the carburetor adjusted by an authorized service

dealer.

Idle Speed Adjuster

Fig. 27

REPLACING THE SPARK PLUG

Use a Champion RDJ7Y spark plug (or equivalent). The

correct air gap is 0.020 in. (0.5 mm.). Remove the plug

after every 25 hours of operation to check its condition.

1. Stop the engine and allow it to cool. Grasp the plug

wire firmly and pull the cap from the spark plug.

2. Clean dirt from around the spark plug. Remove the

spark plug from the cylinder head by turning a 5/8 in.

socket counterclockwise.

Note: Replace cracked, fouled or dirty spark plug.

3. Set the air gap at 0.020 in. (0.5 mm.) using a feeler

gauge (Fig. 28).

0.020 in.

(0.5 mm.)

Fig. 28

CAUTION: Do not sand blast, scrape, or clean

electrodes. Grit in the engine could damage the

cylinder.

4. Install a correctly gaped spark plug in the cylinder

head. Tighten by turning the 5/8 in. socket clockwise

until snug.

If using a torque wrench torque to;

110-120 in.•lb.. (12.3-13.5 N•m).

Do not over tighten.

CARBURETOR SETTING

The idle speed adjuster of the engine is adjustable

though the Air filter/muffler cover (Fig 27).

NOTE: Careless adjustments can seriously damage your

unit. An authorized service dealer should make

carburetor adjustments.

Check Fuel Mixture

Old and/or improperly mixed fuel is usually the reason

for the unit not running properly. Drain and refill the tank

with fresh, properly mixed fuel prior to making any

adjustments. Refer to Oil and Fuel Information.

Clean Air Filter

The condition of the air filter is important to the

operation of the unit. A dirty air filter will restrict air flow

and change the air/fuel mixture. This is often mistaken

for an out of adjustment carburetor. Check the condition

of the air filter before adjusting the idle speed adjuster.

Refer to Air Filter Maintenance.

Adjust Idle Speed Adjuster

WARNING: This unit will need to be running

during idle speed adjustment. Wear

protective clothing and observe all safety

instructions to prevent serious personal injury.

Also, DO NOT set unit on any surface except a

clean, hard area while starting or performing any

adjustments. Debris such as gravel, sand, dust,

grass, etc. could be picked up by the air intake

and thrown out by the discharge opening,

damaging unit, property, or causing serious

injury to bystanders or operator.

If after checking the fuel mixture and cleaning the air

filter the engine still will not idle, adjust the idle speed

adjuster as follows.

1. Start the engine and let it run at a high idle for a

minute to warm up.

2. Set the blower/vacuum mode change-over lever to

the up position (Blower Mode). See Operating as a

Blower.

NOTE: Setting the lever to the blower mode prevents

the vacuum bag from filling up while starting or

running the unit.

3. Move the throttle control and let the engine idle. If

the engine stops, insert a small phillips or flat blade

screwdriver into the hole in the air filter/muffler cover

(Fig. 27). Turn the idle speed adjuster in, clockwise,

1/8 of a turn at a time (as needed) until the engine

idles smoothly.

4. If the unit appears to be idling too fast, turn the idle

speed adjuster counterclockwise 1/8 of a turn at a

time (as needed), to reduce idle speed.

CLEANING AND STORAGE

19

CLEANING THE UNIT

WARNING: To avoid serious personal

injury, always turn the unit off and allow it

to cool before you clean or perform any

maintenance on it.

• Use a small brush to clean off the outside of the unit

and to keep the air vents free of obstructions.
